Quantum is a throwback to a time when people "crafted" products and demonstrated a vested interest in their work. From design innovation to fabrication, Quantum takes an amazingly interactive approach to producing some of the best windows and doors in the Northern Hemisphere. Since 1982, Quantum has developed a national reputation for crafting the finest custom all wood windows and doors. We specialize in solutions to the most creative and challenging residential, commercial and historic projects. Our commitment to integrity, design, and craftsmanship is evident in every window and door we build. Our products are both beautiful and functional. Each piece is handcrafted from the finest species of hardwoods and specially selected softwoods using nonferrous fasteners and hardware. Top architects and contractors regularly rely on Quantum to provide the highest level of design expertise and engineering. This collaborative approach helps Quantum exceed customer’s expectations regardless of the complexity or size of the project.
